Title: Electromagnetic flowmeter
Inventor: OKANIWA HIROSHI
IPC: G01F1/60
Filed: 1994-06-01
Abstract: PURPOSE:To suppress generation of crosstalk between an electromgnetic flowmeter and other line at the time of communication. CONSTITUTION:At the time of communication, a duty signal IDUTY is set at 100% and the capacitor C1 at an integrating circuit 4' is disconnected. A switch SW2 is turned off by the 'H' level of a communication signal TXD and turned on by the 'L' level thereof. Consequently, V2=VREFX{R3/(R1+R2+R3)} is satisfied for the 'H' level of TXD and V2+VREFX{R3/(R2+R3)} is satisfied for the 'L' level. RF is 50OMEGA and the resistance R1, R2, R3 are determined to satisfy the following relationships; RFX20mA=VREFX{R3/(R2+R3)}, RFX 4mA= VREFX{R3/(R1+R2+R3)}. Consequently, the Iout is equal to 20mA for the 'L' level of TXD and equal to 4mA for the 'H' level.
